Reserve is part of the diagnosis
A watch that will run on a full wind but fails to maintain power on the wrist may point toward winding efficiency rather than only escapement regulation.
Noise needs context
Some rotor sound is normal. New grinding, scraping, looseness or dramatic change is not something to ignore.
Poor reserve can come from more than the winding system
A tired mainspring, movement friction or other condition can reduce useful reserve even if the automatic mechanism itself is functioning.
Tell us how long it runs
Tell us approximately how long the watch runs after being fully wound or worn and whether that behavior changed suddenly.
